PocketVault Devlog #1 – PCB Design Complete

Today was a big step for PocketVault.

What I Worked On

PCB Design

I completed the first PCB revision for PocketVault in KiCad.

The board currently includes:

• Seeed Studio XIAO RP2040
• 128×64 SSD1306 OLED display
• Rotary encoder with push button for navigation
• Mounting holes for enclosure integration
• Custom board outline designed for the PocketVault form factor

Interface Design

The entire user interface will be controlled using a rotary encoder:

• Rotate to navigate menus
• Press to select options
• OLED display for viewing entries and settings

This approach keeps the device compact while avoiding the need for a keyboard or touchscreen.
